Sherzan's decision to leave the race comes after the Democratic Congressional Campaign Committee met with Appel about the race on her recent trip to Washington, D.C. But in a statement, he insisted his decision was based "solely upon my individual circumstances."

"Finally, I have made this decision based solely upon my individual circumstances and what I believe to be in my best interest and that of my family," Sherzan said. "Ending my candidacy is very disappointing to me personally."
